Dear Humboldtians and Friends of SHP,

Up till now we had been planning how to organize our meeting with him in June in Krakow to celebrate his jubilee. We know that he also looked forward to this meeting with joy.

Now he is no more with us.

Heinrich Pfeiffer is a man of a legend. Not only was he the Secretary General of the Foundation and the founder of the Big Humboldtian Family embracing thousands of AvH scholarship holders from all over the world, but also a very great friend of Polish people and Poland. Using different methods he intervened in Polish ministries during the difficult time of the 1970s and 1980s, thus opening for us the way to scientific laboratories, libraries and archives in West Germany – the way enabling us to achieve the scientific career.

He is no more with us but the memory of him remains.

This remembrance and our gratitude will now be the leading ideas of the conference ”Limits of Knowledge” in Krakow, devoted to him.
